  1. 1. Gas Chromatography Mass Spectrometry Analysis of Epoxides in Gas Phase Reactions

    University essay from KTH/Kemi

    Author : Stephanie Kylington; [2022]
    Keywords : organic peroxy radicals; unsaturated alkenes; TD-GCMS; Tenax® TA; internal standard; organiska peroxidradikaler; omättade alkener; TD-GCMS; Tenax® TA; intern standard;

    Abstract : En nyligen genomförd studie visade att reaktioner mellan vissa radikaler och omättade alkener är snabbare vid rumstemperatur än vad man tidigare har trott. Dessa reaktioner är viktiga för atmosfäriska oxidationscykler och följaktligen var syftet med detta masterprojekt att beräkna hastighetskonstanterna för dessa reaktioner mellan metyljodid och 1-jodidpentan med tetrametyletylen, isopren och limonen vid rumstemperatur genom att kvantifiera respektive epoxid; tetrametyloxiran, isoprenmonoxid och limonen 1,2 epoxid, som producerades.

  4. 3. Inhibited surface-thiols in Geobacter sulfurreducens : Mercury uptake and methylation rates

    University essay from Umeå universitet/Kemiska institutionen

    Author : Andreas Granström; [2021]
    Keywords : ;

    Abstract : Due to daily human (anthropogenic) industrial activity, a lot of elemental mercury (Hg0) has been released to the atmosphere. The mercury can then spread globally, since mercury has the ability to remain atmospheric for up to a year. When mercury deposits, it can end up in anaerobic environments such as sediments and soil.

  5. 4. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hjörtur Brynjarsson; [2021]
    Keywords : Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

    Abstract : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. READ MORE

  6. 5. A Numerical Calculation Tool Design for the Performance Assessment of a Bench-Scale Thermochemical Heat Storage System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : DIYUE WANG; [2020]
    Keywords : Calculation tool; SrCl2-NH3; Performance evaluation; Mass; Energy; Beräkningsverktyg; SrCl2-NH3; Prestandasutvärdering; massa; energi;

    Abstract : Thermochemical heat storage (TCS) is a technology to convert the heat and cold energy into chemical energy, via reversible chemical reactions, to be stored for heating and cooling applications. TCS technology is gaining interest for its very compact energy storage densities offering attractive thermal energy storage (TES) alternatives to decrease energy-related greenhouse gas(GHG) emissions and contribute to sustainable development.
